I had road debris hang up on my swingarm and rub the edge of my tire just like that. It left all kinds of scraped marks and rubber shreds. I didn't realize it was there, until the tire sucked it through and it cleared itsself
Don't know what the debris was, but it freaked me out when it cleared.

The material was mechanically removed from the side of your tire. It wasn't a result of any out of balance, heavy braking, skidding, overinflation or any other tire fitment reason. For example, a shred of shrink wrap with a little chunk of pallet, protruding staple points, snagged in the plastic, could spend time bouncing around on the junction of tire and swingarm, chewing that edge down. Riding in adverse conditions, like the rain, would make it hard to detect an insidious incident like that.

The fact is, if you tried to manually remove that much material from the tire, it would take a belt/disk sander, razor knife and at least 15-20 minutes of honest work at the bench, to accomplish that kind of damage.

Chewing up a specific edge of the tire, like that, takes outside influence.

Another example is when my muffler wasn't properly spaced away from the new wider rear tire. The muffler clamp wore down the edge of the tire, each time the suspension compressed far enough for contact.

Completely understand. Now that it appears the debris has gone, i'll replace it this weekend and really watch for any wear over the next week.

I hope its not the bearing (causing rubbing on the paralever housing) as it would suck to dump $$$ into a bike I haven't even put 100 miles on yet.

Have you removed the wheel? Just to make sure the spacer is still there. There has been quite a few riders of them K1200RSs that have experimented with removing that spacer to correct their tendency of pulling to the right.

Wouldn't be me doing such things, I have the 5.5 wheel, not much room between the tire/swingarm and I know that a tire may change shape at speed....just enough to rub the swingarm.

But....I'd go with some of the earlier post,just because that bike has been repainted, they never came in white from the factory.
